Ctrl-O. This allows members to create a login to the webpage and pay for their membership through there with PayPal (either manually each period or with a subscription).

For those managing the space the admin logins allow managing membership types, prices, duration, etc as well as assigning RFID cards/fobs to peoples accounts. The typical way this works is that you create a nodes for the doors of your space and set access to them based on a specific membership type and time or just having any valid membership. When a person has paid (in cash and manually entered by an admin or via paypal themselves) for a membership the system keeps track of your status with a database and only lets people in if they've actually paid.

You can also just give people or groups of people access (possibly with time/date constraints) or just make the door be unlocked automatically during "open" hours or for events.
Réseau domotique. Jubito: tutorial. In this tutorial we'll create a simple circuit that sense light using a photoresistor.

What we need: ArduinoPhoto cell (CDS Photoresistor) 10K ResistorBreadboard or perforated pcb Follow the screenshot to wire the photocell and then upload the sketch to arduino.
Blog. We have completed our fingerprint scanner and door lock and mounted it in it’s permanent place.

This is when a scene controller comes in handy. In this example we've used a touch screen to display the scene launch options. The buttons can be customized in the sketch code to your preference. With a little hacking you could even change button functions depending on the time of the day or create a full fledged menu system. If you prefer to keep it simple you can skip the touch display and just attach a few buttons to your arduino to trigger the scene commands. The provided example also displays the time in the top right corner. The touch screen used here did not like to share SPI with the NRF24L01 radio. Demonstration. nRF24L01_Arduino. Projects.

DevDuino Sensor Node V1.2 (ATmega 328)
Introduction devDuino Sensor Node V1.2 (ATmega 328) is a compact Arduino-compatible microcontroller and is designed to build wireless networks based on transceiver nRF24L01+.

DIY Arduino PIR Motion Sensor Lighting & Security. From the minds at We wanted to save energy, and create convenience, by adding motion sensors to our lighting circuits. Maybe you want some notification of an intruder. Both can be done with a PIR Motion sensor. When I walk into a room, the lights come on automatically, and when I leave, shut off after a short period of time. You can choose how long that time delay is in the code. I also wanted a override switch for times I want the light to stay on, or off. So, I took an Arduino, added a PIR sensor, a SSR, a SPDT switch, two 10k ohm resistors and whipped up a small sketch to glue it all together. Original article, and more at. Projet.
